How it works

Binds to glucocorticoid receptors in the cytoplasm, translocating to the nucleus to suppress pro-inflammatory gene transcription and reduce production of cytokines, chemokines, and inflammatory mediators. This mechanism decreases airway inflammation, mucus production, and allergic responses while suppressing intestinal inflammatory pathways in conditions like Crohn's disease.

What to watch out for

Do not stop using budesonide suddenly, especially if you have been using it for a long time — your doctor needs to reduce the dose gradually. Always buy Pulmicort or budesonide from a licensed pharmacy, not from roadside sellers or unverified online shops. If you are using the inhaler or nebuliser, always rinse your mouth after use to prevent mouth infections.

Drug Interactions

Avoid taking with ketoconazole or itraconazole (antifungal drugs commonly used in Nigeria) as they can increase budesonide levels in your body and cause more side effects.
